In Shea s approach to the polyhalogenated cyclohexane 87, derived from a red marine alga, Plocamium sp., a Type II IMDA reaction utilizing a disposable (allyl)silyl tether was used as a key step [29nj. The triene cyclization precursor 88 was readily prepared and underwent Diels-Alder reaction in 74% yield with the expected, complete regiocon-trol affording exclusively bicycle 89. The rigid, bicyclic framework of the cycloadduct...

The Gehdiales are very well known and studied for the production of agars, but studies on their secondary metabolites are rare. A polyhalogenated monoterpene, gehdene, has been isolated from the species Gelidium sesquipedale, harvested in Morocco. This molecule has one of the typical carbon skeletons of the genus Plocamium (Aazizi, Assef, and Faure, 1989). 

Pantoneurotriols were isolated with another polyhalogenated monoterpene present in the Plocamium cartUa -neum of Chile, and are regarded as probable biological precursors of pantofuranoids.
